Hi John,

JK>Borland C++ 3.1 fails.

I have never tried that.

JK>FP12 seems good here too. But I had to use IBM1S506.ADD from MCP2 to
JK>get my SIS IDE controller using UDMA.  And the IBM com.sys driver
JK>from MCP2 works with my PCI serial card.

There's another solution that I prefer, the DaniS506.ADD but as long as
your solution works that's the main objective. There are a heap of other
Danielas drivers that substitute the original IBM supplied ones.

JK>Running a stress test with SIO (1.60d) shows that it uses 100% of
JK>the CPU on an inbound transfer at 115200. The IBM com.sys only uses
JK>3% on the same test. SIO gives the app many small packets, hammering
JK>the CPU.

I haven't checked that, as long as it works it's OK with me.

Have a nice day,

Holger
